Hi, my understanding in victoria is that a property manager must go to VCAT if there is any dispute over a bond. all residential tenancy stuff goes through vcat in victoria but not sure if property managers have some discretion. we are on the other side of the fence at the moment ie. landlords going to vcat so we can keep bond as kitchen and bathroom and garden have not been cleaned or maintained in 2 years. not sure how much disretion a property manager has to be able to charge you $150 for cleaning. they would have to show you a written quote I would think. cleaning is such a subjective thing as clean for one person may not be clean for another but I think it is mainly comparison with the ingoing maintenance report. good luck.
